Chinese Lanterns?

Hi,
I would like to set off some Chinese Lanterns in the evening after our wedding and just want to know if thats allowed and if so has any body had them at theirs, seen them whilst staying at CSA etc? Details please, im so excited.

Hi Randymon,
Thanks for the reply, the lanterns I would like to bring are paper with a small fuel cell inside them which when lit fills the lantern with hot air and they float away, they are 100% bio-degradable. Ive copied a link below for you to see. I have seen them in some pictures on trip adviser but just wanted to check.
